Why I'm Not A Fan of Tony/Ziva

Okay, so I'm going to do some pretty heavy disclaiming up here before I actually get into this because frankly I'm from the Star Wars fandom, and if there's a fandom that knows shipper wars, canon wars, and any other kind of fandom related wars you can think of it's Star Wars.

First of all - I'm not knocking people who like Tony/Ziva.  Each to their own, live and let live. 
Second of all - I'm not saying that I dislike Tony/Ziva because I tend to ship Ziva with Abby or Jenny.  NCIS is probably the most mix-and-match fandom that I've ever seen as far as characters who have awesome chemistry and make totally awesome ships go.
Third of all - I'm not saying that I don't like Tony or Ziva.  I do.  A lot. 

( But here's why I don't think they should be a couple. )
